Y' DEViCE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 286,596, dated October16, 1883.

Application tiledv August 28, 1883. (No modela To all whom tinlay-concern:

Be it known that I, Cnnnrns H. Encin- Bnnoir, a citizen of the UnitedStates, residing at Alden, in the county of McHenry and State ofIllinois, have invented a new and useful Device for Converting' Motion,of which the following is aspeciiioation, reference being had to theaccompanying drawings.

This invention relates to devices for converting motion, and it has forits object to change the reciprocating movement oi' a windmill-pumpshaft int-o a continuous rotary motion. f

To this end it consists of a shaft journaled in the windmilltower andcarrying gearwheels arranged to move in opposite directions, saidgear-wheels engaging with a rack which is attached to the end of thepump-shaft of any ordinary windmill. Thesedevices connect with suitablemachinery for shelling corn, churning, Src., and thus, when the rack isreciprocated by the movement ofthe pump-shaft, this movement will betransmitted to the gearwheels, which will convert it into a continuousrotary motion.

My invention consists in the above-described construction, and incertain other details, as hereinafter fully set forth, and particularlypointed ont in the claims. v

In the drawings hereto annexed, Figure 1 is A a view of a'windmill-tower, showing the arrangement of my improved. devices. Fig. 2is a perspective view of'my improved devices detached. Fig. 3 is avertical longitudinal section on line y y, Fig.V 5; Fig. 4i is a similarview taken at right angles to Fig. 3. Fig. 5

is a horizontal sectionon the line e z, Fig. 3.

- Fig. 6 is a transverse section on the line, m a',

Fig. 4.

Like letters rei'er to corresponding parts in the several figures.

Referring to the drawings, A designates the windmill-tower, of any ofthewell-known forms oi' windmills, and B the pumping-shaft thereof,operated in the usualmanner.

Journaled inthe tower is a shaft, C, which is held from working outthrough its journals by means of collars c, Ahaving set-screws c', saidshaft carrying two setsoi' devices acting independently of one another,said devices Voperating to convert a reciprocating movementV into arotary motion.

D D designate gear-wheels working loosely lar plates E E', secured tothe back of the gear-wheels, said plates having square-shaped blocks F Fformed therewith. Suitablylaround the shaft C, and provided withcircushaped recesses f f are cut from the blocks,

held from turning independently by means of set-Screws h 71.', thelatter working through an the caps is hollowed out, and around the innersurfaces of the rims 'i 'i' is formed a continuous circumferentialseries of ratchet-teeth, j j', the blocks F F', with the pawls, fittingwithin the hollowed-out `portion of the caps, the pawls engaging withthe ratchet-teeth.

The inner portion of It will be seen that the heads g g of the pawls iitwithin the recesses f f', which are shaped to retain the heads and yetallow `free movement of the same, the front ends of the pawls projectinga short distance beyond the i blocks F F', so as to readily engage withthe ratchet-teeth in the caps. Two pawls are used for each of thegear-wheels D D', and engageV with the ratchetteeth in the caps, theextended corner Z of the blocks limiting the play of the pawls.arrangement of the pawls, and the ratchetteeth in the caps are arrangedin different positions for each of the gear-wheels D D. .Thus as shownin the drawings, the position of the pawls G, the manner of iitting thesame in the blocks, and the arrangement of ratchet-teeth j are allreversed in the gear-wheel D, so that when the gear-wheel D is operatedit will revolve independently on the shaft, since the pawls G will 4slip'readily over the ratchetteeth j, while when the wheel D is operated thepawls G will be engaged withthe teeth j', and said wheel D cannot slipor revolve loosely around the shaft.

I designates a loose wheel fitted on shaft A, between the gear-wheels DD', said loose wheel running on a continuous track, J, formed in-` sidethe elliptical -shaped rack or frame K, around the middle portion. Aseries oi' teeth, L, is formed on opposite sides oi' the rack, out

The recesses in the blocks, the

side the track J, the gear-wheels D D meshing with said teeth when therack isreciprocated, while the loose wheel I serves to hold the wheelsin mesh only at a certain depth. The rack or frame is formed at itsupper and lower ends with extensions M, to the upper one of which isattached the pumping-shaft of any ordinary windmill, so that when theshaft is reciprocated a similar movement will be transmitted to therack. As the rackdescends the gear-wheels D D are revolved and engagewith the teeth L, the loose wheel I guiding the gear-Wheels in theirmovements. By the revolution of the gear-wheels, the blocks, with theirpawls, are carried aroundinside the caps, the pawls G of wheel D beingdisengaged from the ratchet-teeth j of the cap II, so that saidgear-wheel will revolve independently of shaft A without turning` itscap, while, the pawls G of the wheel D being engaged with theratchet-teeth j, the cap H will be revolved, there- K gaged, and thusthe cap II will not be opery tion are obvious.

by turning the shaft A. 'Vhen the rack aseends, the wheels D D areoperated in a reverse direction, the pawls G of wheel D being engagedwith the teeth 7 inside the cap II, so that said cap will be revolved,causing the continual revolution of the shaft A, while the pawls G ofthe other wheel, D, will be disenated. This reciprocating movement iskept up,and will be converted into a continuous rotary motion, whichwill be imparted to the shaft A, the latter having at one end apulley,N, connecting by a belt,` 0, with the operating-shaft of a corn-shellingmachine, churn, washing-machine, or any other suitable means.

The operation and advantages of my inven- The construction is simple anddurable, and works with admirable efficiency in converting areciprocating movement into a rotary motion.

. It will be obvious that various modifications may be resorted towithout departing from the spirit or scope of my invention.
